SM04: The Calibrator is a side mission in Deus Ex: Mankind Divided. It is available for Adam Jensen to complete during his first visit to Prague. While this side mission has an achievement, it has another name and depends on the path you take, which means you could miss it (and another achievement) entirely.
You get this mission after talking with Koller and he tells you about the neuroplasticity calibrator that could help Adam use all his augmentations without choosing which ones to disable. Unfortunately, the one who has it, Otar Botkoveli, isn’t exactly on speaking terms with Koller, so you have to go get it from him.
There are two ways to get the calibrator, but only the first has the option of opening up more missions and achievements later in the game.
- Head to the alley behind Tubehouse Electronics to find a sewer entrance with a poker chip paint job. Enter and follow the rugs to the casino entrance and open the door. This will lead to a cutscene of Adam overhearing Otar talking to one of his men, Vano, before Adam walks in. Select straight talk all three times and then accept and he will give you the calibrator in exchange for a couple favors down the road. Now all you have to do is head upstairs to Otar’s office and retrieve it off his desk.
- If you do not want to deal with Otar and the later favors, you can sneak your way in via a number of ways to get to Otar’s office. Instead of being on his desk though, it will be in the safe (4863). You will also have to make sure to stay cloaked or carefully time taking out the guards to access the safe (or just kill everyone).
Whichever option you went with, once the calibrator is in hand, Adam will contact Koller to let him know he got it and the mission will finish.
- If you do not talk with Otar, you will not get the later option to deal with Gallois in Golem City and then the side mission, All in the Family, when Adam returns to Prague, locking you out from both the Honor Holds Us All Together and All in the Family achievements.
- Acquiring the neuroplasticity calibrator prior to meeting with Koller as if trying to unlock the Time Traveler achievement will bypass the mission altogether. If you wish to get this achievement but want the others as well, simply use a separate save file so you then load the earlier one once you get the Time Traveler achievement.
